The Harrison Loring House is a historic house at 789 East Broadway in the South Boston neighborhood of Boston, Massachusetts. It is a 2+1⁄2-story brick mansion, with a mansard roof in the Second Empire style. It has brownstone trim around the windows, a modillioned cornice, and a projecting center section with its entrance sheltered by a shallow portico. It was built in 1865 for Harrison Loring, owner of the City Point Iron Works, a major South Boston shipyard, at which steamships were built in the late 19th century. Loring lived in this house until 1894.

The house was listed on the National Register of Historic Places in 1983 and designated as a Boston Landmark by the Boston Landmarks Commission in 1984
